Keep in mind is that temperature fluctuations can be as bad as a sustained high temperature. I don’t claim to know the science but what I have found is that food stored at a constant 80 degrees will hold better than food stored at 30 in the winter and 90 in the summer. Anecdotally, this is especially true of canned goods I have stored in my home.
We tend to take the power grid for granted, until it fails us. And 'tis the season. “While we love to get outside and enjoy warm weather it's fairly common to experience pop-up thunderstorms and inclement weather,” in the summer, said Liz Pratt, a spokesperson for LG&E and KU, the utility provider in my city. “Utilities, speaking broadly, are continually investing in our electric systems and equipment to make them more resilient. However, during storms, strong winds and storm debris are major culprits that can cause power outages.”
Though its light weight and long shelf life are ideal for navigating harsh conditions, freeze-dried food is probably most famous as a cultural curiosity: Like many Americans, I discovered it in a museum gift shop, gawking at the styrofoam-like ice cream that astronauts used to have for dessert. More recently, I encountered it at a disaster preparedness convention in Raleigh, North Carolina, where smiling, gray-haired preppers manned tables piled with plastic bags full of vegetables, meats, and stews.
